Calcined Quick Lime Lumps - FAQs
Why are Nagaur, Rajasthan quick lime lumps preferred across India?
Nagaur and Khinwsar in Rajasthan sit on one of the purest high-calcium geological limestone deposits in the world. Quick lime lumps manufactured here exhibit exceptional CaO content (up to 92%+), exceptionally low silica (<1.2%), and minimal magnesium, making them the premier choice for demanding steel manufacturing and metallurgical fluxing.
What lump sizes do you supply?
Our standard screening yields 10mm to 50mm lumps, which is the industry standard for steelmaking hoppers and lime hydrators. We can also provide custom gradations such as 20mm to 80mm or crushed 5mm to 20mm grit upon client request.
